PURPOSE: A container structure with improved function and composition is provided to enable users to easily open the container without a separate device, and to reduce the total volume of the container. CONSTITUTION: The container(1) is composed of a body(10), an opening device(20), usually a cap, on one side of the body(10), and a closing part(30) on the other side of the body(10). At least one vertical body folding line(11) is formed on the body(10) so that the body(10) is more naturally folded along the line(11) when the content inside the body(10) is taken out. Also, a volume change-preventing auxiliary folding line(31) is formed in proportion to the area of a closing surface(32). At least one closing surface(32) is formed as the closing part(30) is folded inwardly.
